Article Synopsis
  • * It highlights various techniques like the modified latissimus dorsi musculocutaneous flap and the lateral intercostal artery perforator (LICAP) flap, demonstrating effective results and high patient satisfaction.
  • * The text also mentions the application of different flaps for specific situations such as oncologic resections, weight loss, and implant removal, emphasizing the advantages of utilizing nearby tissues for reconstruction.

Breast cancer is among the most common cancers diagnosed in women, affecting one in eight women per year. Immediate implant-based breast reconstruction has emerged as the predominant approach for postmastectomy reconstruction, with a growing preference for the direct-to-implant (DTI) method over the traditional tissue expander technique. While conventionally, implants were typically positioned beneath the pectoralis major muscle, recent advancements have paved the way for implant placement above the muscle, in the prepectoral plane.

Cancer therapy is facing increasingly significant challenges, marked by a wide range of techniques and research efforts centered around somatic mutations, precision oncology, and the vast amount of big data. Despite this abundance of information, the quest to cure cancer often seems more elusive, with the "war on cancer" yet to deliver a definitive victory. A particularly pressing issue is the development of tumor treatment resistance, highlighting the urgent need for innovative approaches.

Lung cancer is a highly aggressive neoplasm and, despite the development of recent therapies, tumor progression and recurrence following the initial response remains unsolved. Several questions remain unanswered about non-small cell lung cancer (NSCLC): (1) Which patients will actually benefit from therapy? (2) What are the predictive factors of response to MAbs and TKIs? (3) What are the best combination strategies with conventional treatments or new antineoplastic drugs? To answer these questions, an integrative literature review was carried out, searching articles in PUBMED, NCBI-PMC, Google Academic, and others. Here, we will examine the molecular genetics of lung cancer, emphasizing NSCLC, and delineate the primary categories of inhibitors based on their molecular targets, alongside the main treatment alternatives depending on the type of acquired resistance.

Article Synopsis
  • The study examines the potential benefits of universal germline testing for all breast cancer patients, particularly focusing on how it may influence clinical decision-making.
  • Researchers assessed data from a cohort of men and women aged 18 to 90 who had not been previously tested for genetic variants, documenting changes to treatment recommendations based on the testing results.
  • Results showed that a significant majority of patients (83.8% in-criteria and 67.6% out-of-criteria) had at least one change in their clinical management following genetic testing, highlighting the practical implications of testing guidelines.

Purpose: An estimated 10% of breast and ovarian cancers result from hereditary causes. Current testing guidelines for germ line susceptibility genes in patients with breast carcinoma were developed to identify carriers of BRCA1/ 2 variants and have evolved in the panel-testing era. We evaluated the capability of the National Comprehensive Cancer Network (NCCN) guidelines to identify patients with breast cancer with pathogenic variants in expanded panel testing.
